OF MIAMI, FLORIIIJJSL SPRINKLER i Application filed May 25,

a The present invention relates to improvements in sprinkler heads and more particularly to the type of head set forth in my U. S. Patent No. 1,165,202 in which a rotary member is disposed antifrictionally within a support so that water issuing under pressure from the lower part of such support against said rotary member imparts rotation to said member and coacts therewith to producea spraying or raining efiect, the main object-of the present invention being the provision of means .whereby the upper bearing is lubricated by the water during thespraying period and by means of which said bearing is kept clean by the flow of water therethrough.

Another object of the invention is the provision of means at the lower portion of the rotary member whereby the water issuing from the nozzle is assisted by the admission of air above the nozzle in keeping the nozzle and lower bearing clear of dirt.

In the accompanying drawings Figure 1 is a perspective view of a complete sprinkler head embodying the invention;

Figure 2 is a vertical central view through the sprinkler head, the supporting member and the outlet pipe being indicated in broken lines;

Figure 3 is a view partly in elevation and Figure 4 is a top plan view with the upper portion of the supporting frame removed.

Referring to the drawings the numeral 5 designates the outlet end of a water supply pipe and 6 the supporting rod or member for the sprinkler head body 7 v The body 7 comprisesa cap 8 internally threaded as at 9 for attachment to a water supply pipe or hose 5, and a tubular portion 11 of smaller internal diameter than the cap 8 rising from said cap. The tubular portion 11 is internally screw threaded as at 12 and is internally enlarged at its lower end, thus forming a recess at the upper end of the cap 8. An externally screw threaded tubular nozzle member 13 is screwed into the tubular portion 11 from the lower end of the latter and has its upper end formed as a bearing member preferably as a truncated cone, as

portion 11 of the sprinkler head, has a boss 17 concentric with the member 11 and spaced thereabove. A screw threaded aperture is formed in said boss, in axial alignment with the tubular portion 11, for the reception of an upper bearing screw 18 which is locked in adjusted position by means of the lock nut 19.. *The'end of this bearing screw is pref: erably conical, as at 20, the purpose of which will presently appear.

A' spraying member 21 is rotatively mounted in the frame 16 between the upper end'of the nozzle member 13 and the lower end of the screw 18. This spraying member comprises a collar 22 having a spray-directing propeller extending upwardly there- A seat 27' shaped complementally to the 1 lower end of the screw 18 to receive the lower end of. said screw is formed in the top ofthe propeller or wing 25 coaxially with the collar 22, and a similar seatshaped complementally to the upper end of the nozzle member 13 is formed in the lower side of the collar 22 to receive the upper end of the nozzle member 13. The collar 22 has an axial bore 23 coaxial with but of larger cross section than the bore of the nozzle member 13 and a plurality of radial passageways 24 ex tend from the periphery of the collar 22 to said bore 23. A bore 26 extends through the propeller or Wing 25 coaxially with the bore 23 to the bottom of the seat 27. 'Thus the spraying memberv2l is rotatively supported at its lower and upper ends, respectively, by the nozzle member 13 and screw 18.

- Tater admitted under pressure from a pipe or hose 5 into the collar 8 will flow through the axial bores of the nozzle meinber 13 and collar 22 and be directed against bore of the collar 22 will draw air into the latter bore through the radial passageways 24 so that the jeteof water mixed with air issuing from the axial bore of the collar 22 will draw out any dirt which may have lodged between the upper end of the nozzle member 13 and the seat of the collar 22. At the same time a portion of such jet will enter the bore 26 of the propeller or wing 25 and lubricate the bearing surfaces of the lower end of the screw 18 and the seat 27.

From the foregoing description it is evident that a sprinkler head constructed according to and embodying the present invenion will provide a water lubricating rotary member in which the water also acts to remove any dirt or grit or even the abrased material of the nozzle or sprinkler head, so that the member is rotated freely.

I claim as my invention 1. A sprinkler head, including an attaching member, an open frame carried thereby, a bearing member carried by the attaching member and provided with a nozzle opening, an adjusting screw mounted in upper portion of the frame concentric with the nozzle opening, and a member rotatable between the nozzle member and the adjusting screw and providedwith two bores alined with one another and said nozzle opening, one of said bores serving as a jet nozzle and the other bore leading to the lower end of said screw.

2. A sprinkler head according to claim 1 in which the rotatable member has a plurality of openings extending radlally from its 7 nozzle bore.

3. A sprinkler head including a hollow attaching member, a nozzle member projecting from said attaching member and of which the end forms a bearing member, an open frame carried by said attaching member and having an interiorly screw threaded opening spaced from and concentric with the nozzle member, a screw in said screw threaded opening, and a member rotatable in said frame and having oppositely disposed bearings into which the bearing end of said nozzle member and the end of said screw, re spectively, extend, said rotatable member having two bores longitudinally alined with one another and with said nozzle member and screw, each of said bores communicating with one of said bearings, and the bore .ad-

jacent said nozzle member forming a jet nozzle.

' 4. A sprinkler head according to claim 3 in which the rotatable member is provided with a plurality of radial bores leading from its exterior to its jet nozzle adjacent the bearing end of said nozzle member.

5. A sprinkler head according to claim 1, in which the ct nozzle of the rotatable member is of greater cross-sectional area than the nozzle opening of the bearing member and a plurality of bores extend radially from the exterior of the rotatable member to its jet nozzle at a point adjacent to the bearing member carried by the attaching member.

In testimony whereof I have hereunto set my hand. A 7
